Cooperative Automated Transportation (CAT)

Cooperative Automated Transportation

Roadway safety in a cooperative automated world

Highway automation is not years away, or even days away. It’s here now, causing a number of state transportation agencies to react with initiatives related to preparing and supporting Connected Automated Vehicles (CAVs) on U.S. roadways.


Connected and Automated Vehicles (CAVs)

Cooperative Automated Transportation (CAT) deals with CAVs, which are vehicles capable of driving on their own with limited or no human involvement in navigation and control. Per the definition adopted by the National Highway Traffic Safety Administration (NHTSA), there are six levels of automation (Levels 0-2: driver assistance and Levels 3-5: HAV), each of which requires its own specification and marketplace considerations.


Vehicle-to-Everything (V2X) and Connected and Automated Vehicles (CAVs)

For traffic safety, vehicle-to-everything communications is the wireless exchange of critical safety and operational data between vehicles and anything else. The "X" could be roadway infrastructure, other vehicles, roadway workers or other safety and communication devices. ATSSA members are at the forefront of these technologies, and are working with stakeholders across new industries to see these innovations come to life.


Sensor Technology

CAVs rely on three main groups of sensors: camera, radar, and Light Detection and Ranging (LIDAR). The camera sensors capture moving objects and the outlines of roadway devices to get speed and distance data. Short- and long-range radar sensors work to detect traffic from the front and the back of CAVs. LIDAR systems produce three-dimensional images of both moving and stationary objects.

Midyear Meeting adds Roadway Worker Protection session to agenda

Pam 0 5839 Article rating: No rating

This year’s Midyear Meeting adds a new council focused on roadway worker protection to the lineup.

The addition evolved from the Roadway Worker Protection Summit, which was heavily attended during ATSSA’s 2021 Annual Convention & Traffic Expo held online in February, said ATSSA Vice President of Education and Technical Services Donna Clark.

She said the topic resonates with everyone in the roadway safety industry and, unfortunately, the statistics on injuries and deaths aren’t improving.

Congressional Road Safety Caucus puts spotlight on safety

Transportation and safety proposals this year offer optimism for roadway safety advocates

Pam 0 5564 Article rating: 4.0

One of the ways members of Congress shine a light on a specific issue is through the formation of congressional caucuses. Reps. Chris Pappas (D-N.H.) and Bruce Westerman (R-Ark.) have done exactly that in creating the bipartisan Congressional Road Safety Caucus this year.

One of the first steps came on April 14, when Reps. Tom O’Halleran (D-Ariz.) and Bruce Westerman (R-Ark.) introduced the High Risk Rural Roads Safety Grant Program Act in the House. The Act would create a new competitive grant program for local jurisdictions and tribal nations to focus federal funding on rural and tribal road safety projects.

Funded at $600 million annually, this proposal would give a needed boost to targeting safety challenges on these rural and tribal roadways.

Other roadway safety proposals are also being considered on Capitol Hill.

House Republicans release transportation reauthorization proposal

Pam 0 4945 Article rating: No rating

Republican members of the House Transportation and Infrastructure Committee, led by Ranking Member Sam Graves (R-Mo.), today released their version of a transportation reauthorization ahead of likely Committee action in early June. The language, which is narrower in scope than the House-passed transportation bill last year, would spend $400 billion over five years on federal-aid highway projects, an increase of 32% over current funding levels.

Dubbed the Surface Transportation Advanced through Reform, Technology & Efficient Review Act 2.0 (STARTER Act 2.0), the legislation includes increases to the Highway Safety Improvement Program (HSIP).

MASH scoping study discussed during AASHTO Virtual Spring Meeting 2021

Pam 0 5708 Article rating: No rating

During AASHTO's 2021 Virtual Spring Meeting on Monday, the Council on Highways and Streets (CHS) gathered to provide updates from various stakeholders. The discussion included an update on the Manual for Assessing Safety Hardware (MASH) scoping study to determine the feasibility and potential next steps to convert MASH into a set of performance specifications.

Joyce Taylor from the Maine Department of Transportation (MaineDOT), who serves as design vice chair with AASHTO, gave an update on the MASH scoping study conducted by Texas A&M Transportation Institute (TTI). She discussed the challenges related to current testing procedures and the gray areas within the existing manual that lead to a lack of consistency, as testing may be conducted differently by facilities.

The scoping study, conducted by TTI and sponsored by AASHTO, was completed in April.

Federal Highway Administration (FHWA) Acting Administrator Stephanie Pollack joined ATSSA members today for day one of the Association’s two-day Legislative Briefing & Fly-In being held online this week.

Pollack stressed the importance of roadway safety and referenced next week’s National Work Zone Awareness Week as she engaged in a conversation with ATSSA Vice President of Engagement Nate Smith and responded to member questions.

More than 100 ATSSA members registered for the Legislative Briefing & Fly-In, which is organized by ATSSA’s Government Relations Team and is a member benefit. Members are scheduled to take part in more than 60 meetings with members of Congress and legislative staffers on Thursday.
